JAMES R. ALLGIRE, OF INDIANAPOLIS, INDIANA, ASSIGNOR TO THE ALLGIREMANUFACTURING COMPANY, OF SAME PLACE.

VENEER-DlSH-BLANK MACHINE.

SPECIFICATION forming part of Letters Patent No. 261,120, dated July 18,1882. Application filed March 23', 1882. (No model.)

To all whom it may concern Be it known that I, JAMES R. ALLGIRE, aresident of Indianapolis, in the county of Marion and State of Indiana,have invented a new and useful Improvement in Veneer-Dish-BlankMachines, of which the following is a specifica tion, having referenceto the accompanying drawings.

My invention relates to an improvement inmachinesformakingveneerdish-blanks,\vhereby the form of said blanks iscut and scores for bending are made in the surface of a cylindricalblock before the veneer is out therefrom.

It consists in the construction of the'die for making, cutting, andscoring said forms, whereby the die is prevented from cutting too deep,and in the general construction and arrangementof parts, whereby blankscut to a proper form and properly scored for bending into shape are outcontinuously from a revolving cylindrical block.

The accompanying drawings illustrate my invention.

Figure 1 is a plan. Fig. 2 is a vertical longitudinal section.

Like letters refer to the same parts in both figures. r

a represents a cylindrical block of wood, which is firmlyheld endwiseand centrallybetween the spindles b, in the manner usual inveneer-machines. Two frames, 0 d, are arranged to slide upon ways 6 e ee. Said frames are connected at each end by right and-left screws ff,which, by their simultaneous revolution, cause frames 0 and d tosimultaneously approach or recede from block a. Frame (1 carries aveneer-knife, g, for shaving off veneers from block a, and adjustablespurs i i for cutting said veneers to the proper length. Frame 0 carriesin suitable bearings a metallic cylinder, 1, which revolves byfrictional contact with block a. Firmly set in grooves in the surface ofcylinder l are longitudinal cuttingknives m and n and transversescoring-knives o 0. Knives'm and a project above the surface of thecylinderjust the thickness of the veneer to be cut from block a, whileknives 0 project only about one-half as high, the purpose of knives onbeing to separate the blanks from each other and the purpose of knives nto cut clear through or slit the blanks ashort distance from each end,for the purpose of forming the ends of the dish. The purpose of knives 0is to cut or score the blanks about half through, so that they will bendin the proper places. It is important that knives m and a do not cutfarther into the log than just the thickness of the dish-blanks, becausethe cuts for the blanks in successive layers of veneer do not comedirectly under those in the preceding layers, and a partial cutin thewrong place would cause the dish to crack in drying, and it is for thisreason, also, that it is important that cylinder I must revolve byfrictional contact with block a, so that the surface of the cylinderwill form a backing to prevent the possibility of variation in the depthto which the knives penetrate the block, and also to insure the samewidth of blanks without regard to the diameter of block a. At the pointsof intersection between knives a and scoringknives 0, knives o are for ashort space of the same height as knives 'n. This is for the purpose ofcutting clear through the blank at this point, to prevent the dish fromsplitting at the bottom corners during the process of drying.

The operation of my machine is as follows: Frames 0 and d are caused toapproach block a by means of screws funtil cylinderl and knife geomestronglyin contact with block a. Block a is revolved by spindles 1),between the ends of which it is clamped. As block a revolves, cylinder(1 is also revolved by contact therewith, and the form of the dish-blankis impressed or cut in the surface of the block a, as it revolves, thelength of the blanks being determined by the spurs i i, which also outinto the block as it turns against them. As the block continues torevolve, knife 9 shaves a veneer off, and the dish-blanks fall separatedand scored ready for folding into shape.

I am aware that veneerdish-blank machines in which the form of the blankwas cut in the face of a block with parallel surfaces, and a 10different depths, for the purpose described, a

knife for separating the veneer from the log, anda mechanism for causingsaid cylinder and saidseparating-knife to simultaneously approach thelog, all combined substantially in the manner and for the purpose setforth.
